Specification of Letters Patent.

Patented March 30, 1909.

Application filed August 17. 1906. Serial No. 331,061.

To all whom it may concern:

Be it known that I, GEORGE W. Banner, a citizen of the United States, residingat Louise, in the county of Wharton, State of Texas, have invented certain new and useful Improvements in Gang llowsz and I do hereby declare the following to be a full, clear, and. exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to plowsand more particularly to wheel plows, and has for its object to provide a plow including a pluralityof plowing units which will be sns ceptible of independent adjustment and which will also be arranged for n'iovcment with respect to each other automatically to compensate for inequalities in the surface of the round.

Another object is to provide a novel an rangemcnt oflparts which will tend to produce an efiicient implement of the kind described.

Other objects and advantages will be apparent from the following description.

In the drawings forming a portion of this specification, and in which like characters of reference indicate similar parts in the several views, Figure 1 is a side elevation of a complete plow. Fig. 2 is a top plan view. Fig. 3 is a transverse section on line 33 of Fig. 1, taken in the plane of the ground wheel slides. Fig. 4 a section taken on line at --4 of Fig.9 transversely of the plow, illustrating the conmyction of the units and the balancing gear. Figs. 5 and U are transverse sections taken ,respectively 1 on the lines 5--5 and (3 6 of figs. :2 and 1. t The present invention shown in the drawmgs, comprises two units and 6, which ini of the path of movement of said hook, so

its hook clude plow b ams 5 and 6', respectively, the rearward'portions of said beams being turned downwardly and forwardly to form stocks 7, the lower ends of which have shares 8 secured thereto. The beam 5' extends a slight distance beyond the rear end of the beam 6. thus disposing the shares ip'.,differentplenes. ,1, The stock of the beam 5 has secured thereto a pair of rearwardly extending straps 9. betweei-i which is disposed a slidable upright 10 to whose lower end is swiv- .eled a rearwardl extending arm E u on 65 the ofiset free en of which a trackegw eel raised or l )\\'(fl' :.-Ll by means of a lever C uh-ruined upon the stock of said beam and connected by a link I) with a rack segment 1 with a series of teeth. A formedmpon the upright, the segment being pivoted between the straps J. m-tical movement of the upright, however, as well as swinging movemcni of the arm E is normally priyrented, owing to the provision of a latch 13 .pivoted centrally to a strap secured to the stock of the beam 5' beneath the first-mentioned straps, tho grooved or hooked end of the latch being held in yielding engagement with the arm E by a COIHPIBSS'lOH spring 9 interposed between said stock and the upper end of said latch, the extreme upper end oi which latter connected by a link 10 with a foot-Lever 11' pivoted to the outer face of the beam 5'. Depression ofthe fo0tlever will therefore release the latch end from engagement with the arm. E, to permit vertical. movement of the tracker Wheel, the lover C for operating; said wheel being held in adjusted position by a dog-and-rack mechanism 12. swinging movement of said arm being likewise possible upon such release. The beam 5' is further provided with a horizontal inwardly-cxtending U- shaped bracket F, whose members are connected ii'itermediate their ends by an arcuaic strap H extending upwardly therefrom, which strap has pivoted thereto a lever G UOllllt-Clfll by a link K with the adjacentend of a horizontal arm I which is pivoted centrally between the inner ends of the members of the bracket F. and is (lispo cd transversely of the beams 5 and 6,

Tin.- free end of the arm I is adapted for engagement with a hook L carried by the beam 6, and when such free end is at the downward limit of its movement, it lies out that said beam may rise, to brin above said arm, whereupon, the atter may be reingaged with the hook through the medium of the lever G, so as to prevent downward movement of the beam 6' with respect to the beam 5. Each beam carries a tracker wheel Z which is disposed in advance of the corresponding share 8.

The inner face of each beam has secured thereto intermediate its ends, the vertical arm 27 of an L-shapcd bracket 26, vthe horizontalanms 28 of said brackets extending finwardlv toward each other and being pr0- 11 is 'nevolubly mounlidr The uptight is 1 vided with depending front and rear flanges v 29. These flanges serve to support plates 34 and 35, above referred to, are disposed ends of the plate 33, to hold the latter in vertical movement with respect to each plates 25.

held yieldably against vertical movement 2-1 and 25 secured thereto and d sposed i transversely of the beams, as shown in Fig. 2, said plates resting upon the inturned lower edges of the flanges 29. The lates of the beam 5 are heldm s aced re ation to each other by means of a lock 30 disposed therebetween, and extending inwardly beyond the ends of the plates. At its inner end, said block is provided with pairs of oppositely extending lateral wings 3=land 35, the space between said pairs of wings bein reduced and provided with a roller 31 reigolhhle thereon and movable in a vertical $101532, formed in a vertical plate 33, which is secured to the inner ends of the plates 24:

and 2.6 of the beam 6. The pairs of wings against the opposite sides of the plate 33, thus preventin disengagement of the roller 31 from the sot 32 and in such manner, connect the units 5 and 6. The pair of wings 3a is formed integral upon the block 30, while the pair 3:) is removably connected therewith, so as to permit their attachment subsequent to the disposition of the roller within its slot. The plates 2-l and 25 of the beam 6 are held in spaced relation to each other by bolts 36, one of said bolts being engaged with the central portion of a brace 37, whose ends are fastened to the vertical position.

By reason of the disposition of the roller 31, within the slot 32, it will be ap arent that the two units 5 and 6 are susceptible of other. These two units are provided with a balancing gear comprisin a pair of sprockets 3S and 89, revolub l y mounted adjacent the forward faces. of the plates 25 upon the bolts which-connect said plates with the corresponding plates 24, and a third sprocket 40 mounted upon the upper end of the plate 33, said sprockets being engaged by a chain 42, whose central portion passesv over the sprocket 40, while its ends pass beneath the sprockets 38 and 39 and are connected to helical springs 11, secured at their outer ends to the outer ends of the The two units 5 and 6 are thus with respect to each other.

Between each pair of the plates 2i and 25, outwardly .of their respective low beams, there is secured a vertical bloc 43, having longitudinal guide passages 44 formed therein, in which passages are disused a pair of vertical slides45, whose ower ends are rovided with lateralspindles 46, non w ich the round wheels 47 are revolu ly mounted. he upper end of each slide 45 carries a horizontal pin 45 u on which a sprocket wheel 48 is revolub y mounted; each plate 24 is likewise provided at its outer end with a similar pin carrying a sprocket wheel 49. The sprockets 48 and -19 of each unit are engaged by a sprocket chain 51, the upper end of which is connected by a coil-spring 50.with the adjacent block 48. The lower. end of each chain is connected to one end of a coil-spring the opposite end of one of said s rings being connected with the plate 33, ant that of the other springto one of the laterallyextendin wings 34. The slides 45 are thus held yielt ably against vertical movement, as vwill be readily understood. The pairs of plates '24 and 25 and the parts carried thereby, thus form what may be termedtrans ver.-.'- sills which are carried by the. plow beams and are connected at their inner ends for bodily vertical movement with respect to each other.

One of the brackets 26 has secured thereto a rearwardly-extending metal plate 53, whose upwardly bent rear portion 54 forms a spring support for a seat 55, said support being connected to the beamb' by a bracket 56.

The operation, it is 'thought, will be understood without detailed description. As the machine is moved over the ground, the ground-wheels 47 are free to move vertically to compensate for inequalities of the surface, though they are retarded to some extent by the spring mechanism described above and by reason of the arrangement permitting of independent vertical movement of the two units 5 and 6, one of the shares may rise to pass over a hummock which is passed by the other share.
